Writers should first be readers. If you don’t read, you’ve not the tools to write. Don’t take my word for it. I know I’m not the first novelist to give this advise. It’s been said by so many who are more popular, more established. So I guess it’s a proven fact.
Never assume you’re good just because your friends/relatives/etc tell you, and would bet their lives, that you are. They’ll always give you the thumbs up. They don’t work with the publication, they don’t know what the parameters are for the approval of a manuscript. Even if you’re good, that doesn’t necessarily mean your work will merit approval from the powers that be.
If you believe you’re a good writer, it’s no use making a status of it. JUST WRITE AND GO SUBMIT YOUR MANUSCRIPT TO A PUBLISHER, then we’ll see if you really are good.
